Influence of Landau level mixing on the properties of elementary excitations in graphene in strong magnetic field
Yu. E. Lozovik, A. A. Sokolik
Massless Dirac electrons in graphene fill Landau levels with energies scaled as square roots of their numbers. Coulomb interaction between electrons leads to mixing of different La…

Collective excitations on a surface of topological insulator
D. K. Efimkin, Yu. E. Lozovik, A. A. Sokolik
We study collective excitations in a helical electron liquid on a surface of three-dimensional topological insulator. Electron in helical liquid obeys Dirac-like equation for massl…

Spin-plasmons in topological insulator
D. K. Efimkin, Yu. E. Lozovik, A. A. Sokolik
Collective plasmon excitations in a helical electron liquid on the surface of strong three-dimensional topological insulator are considered. The properties and internal structure o…
